Coffee shop customers were stunned when a powerful storm smashed a glass door. <br /><br />Dozens of staff and guests were inside the store when gale force winds and heavy rain struck Nonthaburi, Thailand, yesterday (June 5).<br /><br />The powerful gusts tore one of the glass entrance doors from the hinges and flung it to the ground sending shards of glass spraying across the wooden floor. <br /><br />Shocked customers ran for cover while two staff battled to hold the remaining door in its place to prevent it from also smashing. <br /><br />Outside the coffee shop, a security guard was seen struggling to stay on his feet before scrambling inside the store to take refuge.<br /><br />Onlooker Porped Mandarin said: ''We had a front-row view of the powerful storm. The door smashed and the wind and rain were blowing inside the restaurant. <br /><br />''It was a very sudden, intense storm. The strong winds passed quickly but it carried on raining for an hour.''<br /><br />Sub-tropical Thailand and other countries in the region are experiencing unpredictable storms and rain after the onset of the monsoon rainy season which lasts from June until late September.
